摘要: Epidermoid, small cell undifferentiated, and adenomatous types of bronchogenic carcinoma were all shown to be increased among uranium miners. This was done by use calculations expected numbers for each the major histologic types. The predominance undifferentiated types, however, so great that it appeared only type whose frequency elevated in earlier, relative distribution studies. same three have been cigarette smokers, but with different frequencies. These findings are consistent Kreyberg's hypothesis epidermoid carcinomas lung closely related, principal is affected inhaled carcinogens, even though adenocarcinomas also some extent.
